The toggleblock25 which engagedat one of itsfsides bythe plates'QQ, isgrooved ya'tits'oppositeside to receive the extremity of a toggle 25whose other end engages a die 8 set-inl a recess in the lower portion ofthe moving aw 8.

The protruding ends of the rods 5 which secure the fixed jaw 4 betweenthe sides 3 of the frame, project through circular eyesl formed at theextremities ofr U-shapedyoles the therewith yassociated' jaw 8, relativetol the fixedjaw 4. yHaving thus be readily understood.

The ore to be reduced is fed between the two jaws and the 'sides of theframe 2 which as usual are provided withcheek plates 29.

The working facewof the face plate 7 of themmovableI jaw 8T extendsparallel and in juxtapositionto the portion 6 at the lower extremity'oftheworking face of the fixed jaw 4 and yit is inclined from theperpendiculartoward the' 'latter so that the ore while ybeing ycrushedby the action of the moving jaw is atthe'y same time compelled tol movedownwardly. "f

rThe crankshaft 9 when rotated, imparts to vthe, upper portionof the jaw8 acircular` movement abouty a 'ixed'l transverse axis, while thelowerportion of the jaw movesy correspondingly by reason of the inclinedposition of the toggle 25 the extremitiesof which engage the die `8c andthe toggle block 23. The result is `that the angle between the workingfaces of the two jaws re` mains. substantially unchanged and thecrushing action upon the rock fed between the same is produced by adirect lateral movement of the j awwdtowardthe iixed jaw combined witha" downward grinding motion. After the roel; hasbeen reduced between theupper portions of the two jaws it is further comminuted to a fineness ofuniform size between the portion 6 of the face of the fixed jaw and thetherewith engaging lower` part of the'face of the movable jaw.

The lyokes 2T which hold the abutment 18 against rearward motion,receive the greater part kof the strain to' which the y'Crusherrame isordinarilysubject 'and the latter may, for this lre'ason, .beconstructed of lighter material rto reduce the weight and ycostoffm'anufacture of the machine.
